Don't think anybody manufactures Lisp Machines anymore, unfortunately. I heard DKS used to sell old Symbolics stock a few years ago, you might try shooting him an e-mail; I assume you're aware they're ~30+y/o hardware and whatnot. You could also find yourself the unofficial port of Open Genera to Linux/x86 if all you want is to experiment with the software (which is what made the Lisp Machines shine, however cool the hardware was); or Portable Genera, but good luck getting your hands on that. Emulators for multiple of the machines exist, with varying degrees of completeness. Interlisp-D, which originally ran on the Xerox D-machines and is very different to the MIT-descended Lisp systems, got open-sourced a couple years ago and is available and maintained as well, for a different perspective.
